Abstract

Die Erfindung betrifft ein Wellgetriebe mit einem starren Stützring (1) mit einer zylindrischen, innenverzahnten Stützfläche (3), mit einer radialflexiblen Abrollbuchse (5) mit einer verzahnten Außenmantelfläche (7), mit einer mit einer Antriebswelle (11) verbundenen Antriebseinrichtung (30), durch welche über eine Vielzahl von Stegen oder Stößel (40) ein oder mehrere erste Umfangsabschnitte mit der Stützfläche (3) des Stütztringes (1) in Eingriff gehalten ist, wobei jeder der Stege oder Stößel (40) zumindest an einem seiner beiden Enden eine schlitzartige Nut hat und die Stege oder Stößel (40) sind mit einem ringförmigen Band einstückig aneinandergeformt, wobei das ringförmige Band mindestens annähernd auf halber Länge der einzelnen Stege oder Stößel (50) angeformt ist.
